DETAILED DESCRIPTION

Hereinafter, Flippers worn with shoes according to the present disclosure for achieving such an object can be used as a flipper function by wearing a plate-shaped fin portion on the front of a shin, or can accommodate the flipper by folding a portion of the fin portion on a foot of a shoe. Accordingly, the flippers can be easily used both in and out of water.

Hereinafter, a preferred embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

FIG. 2 is a side view illustrating a state of wearing flippers worn with shoes according to one embodiment of the present disclosure, FIG. 3 is a front view illustrating a fin portion of the flippers worn with shoes according to one embodiment of the present disclosure, and FIG. 4 is a cross-sectional view illustrating a cross section taken along line a-a of FIG. 3.

Each of the flippers worn with the shoe according to the embodiment of the present disclosure includes a fin portion 100, a shoe portion 200, and a fastening portion 300.

The fin portion 100 is worn on the front of a shin of a user, and the entire outline of a body 110 is formed in a trapezoidal plate shape having a short upper side. A height of the trapezoidal body 110 should be formed smaller than a height of a knee bone when wearing a shoe. If the height of the body 110 is higher than the height of the knee bone, it may cause discomfort to walk when folded. The height of the body 100 is similar to a height of the shoe, but may be set to a height that does not interfere with walking. It is confirmed that lift is generated even with a width of the fin placed on the left and right sides of the shoe. The body 110 is cut upward from a center of the lower side of the trapezoidal shape to a size corresponding to the width of the shoe portion 200 to form the instep seating part 120. The instep seating portion 120 has a width corresponding to the width of the shoe portion 200, and a height thereof is set to correspond to a height of an instep of the shoe portion 200, and thus the shoe portion 200 is coupled with the fin portion 100 in a state in which a position corresponding to the instep is inserted into the instep seating portion 120. An end portion of the instep seating portion 120 is coupled to the shoe portion 200 using an adhesive or sewing. Side portions 130 a and 130 b are formed on both sides of the instep seating portion 120 so as to generate a propulsive force using the resistance of water together with the shoe portion 200 by being positioned on both sides of the shoe portion 200. The fin portion body 110 includes a plurality of protrusions 140 to form a groove along a longitudinal direction. The protrusion 140 may guide a flow of water to reduce on a drag applied to the fin pin portion 110 when the user paddles with feet in water with wearing the flippers. This reduces burden on the ankles and legs of the user and reduces risk of fatigue and injury. Meanwhile, a fold line 111 is formed to be perpendicular to a longitudinal direction of the body 110 of the fin portion 110. The fold line 111 has a thickness smaller than that of other portions of the body 110. Accordingly, the fin portion body 110 is folded to be perpendicular to the longitudinal direction and can be attached and folded to the shoe portion 200. A first adhesive member 150 is formed at a center of a front upper end of the fin portion body 110, and preferably, a second adhesive member 210 is formed, which is adhered to the first adhesive member 150 at a position meeting an upper end when the body 110 of the shoe portion 200 is folded.

Meanwhile, referring to FIG. 4 which is a cross-sectional view taken along line A-A of FIG. 3, in the fin portion 100, a center portion of the body 110 in the longitudinal direction is recessed, that is, a portion where the body 110 meets the shin when wearing the flipper is recessed. Accordingly, it is possible to prevent the fin portion body 110 from turning after wearing the flipper, and provide a good fit.

Preferably, the fin portion of the flipper according to the embodiment of the present disclosure uses a medium material rather than hard or soft material. It should be light when worn, and it is desirable to be made of a material that can minimize water resistance while creating propulsion.

The shoe portion 200 may be sandals, aqua shoes, and sports shoes. A scope of the present disclosure is not limited by shapes of the drawings. Since the flipper function is used in water, it is preferable to apply sandals or aqua shoes as the shoe portion 200. It is preferable that the shoe portion 200 includes a second fastening device 330 described later on both sides.

The fastening portion 300 includes a band 310, first fastening devices 320 which are coupled to both ends of the band 310, and second fastening devices 30 which are formed in a shape corresponding to each of the first fastening devices 320 and fastened. Each of the first fastening device 320 and the second fastening device 330 may use a buckle, but the scope of the right is not limited thereto. As illustrated in FIG. 2, the band 310 is coupled to at least one position where the body 110 of the fin portion 100 meets the shin when wearing. The band 310 may be coupled to a front or rear surface of the body 110, or may be coupled to a side end thereof. A plurality of bands 310 may be coupled to be firmly coupled a calf of the user. The first fastening devices 320 are respectively coupled to both ends of the band 310, and the first fastening devices 320 may be arranged corresponding to male and female so that they can be coupled to each other. The second fastening devices 330 are disposed on both sides of the shoe portion 200 and are arranged by male and female settings so as to be coupled to the first fastening device 320, respectively.

FIG. 5 illustrates a state in which the body 110 of the fin portion 100 of the flipper according to one embodiment of the present disclosure is folded. The body 110 is folded along the folding wire 111 to reach the instep of the shoe portion 200. The first adhesive member 150 of the body 110 and the second adhesive member 210 of the shoe portion 200 corresponding to each other are coupled to prevent the fin portion body 110 from moving when walking. In addition, the first fastening device 320 coupled to an end portion of the band 310 coupled to the body 110 is combined with the second fastening device 330 formed on the shoe portion 200, and thus, discomfort is avoided when walking with wearing the flipper. Meanwhile, when the flippers are worn for use, the first fastening devices 320 at both ends of the band 310 may be coupled to each other to wrap around the calf of the user as illustrated in FIG. 2.

According to another embodiment of the present disclosure, when a length of the body 110 is set to correspond to the height of the shoe, and when the body 110 is used as the flipper, the body 110 can be used without fastening the body 110 to the calf with a separate fastening device.

FIG. 6 is a view illustrating a state when swimming with the flippers worn with shoes according to one embodiment of the present disclosure. When performing a kick during swimming, the fin portion 100 is disposed as illustrated, and thus the fin portion receives the lift of water according to the movement of the foot and generates a propulsive force.

According to the flipper configured as described above, the fin portion is detachably fastened to a shoe, and thus there is no hassle of wearing and taking off before and after entering water. In addition, there is no inconvenience of walking and acting by wearing the flippers for a purpose of protecting a foot or working before entering water. Moreover, there is an effect of serving a double purpose such as acceleration of underwater work and underwater movement, and underwater action, as well as protection of feet after entering water. In particular, the flipper is easy to walk in a valley or on a seashore, the flipper has an area that can receive sufficient resistance to water from the fin portion in the water, and thus, it is possible to obtain a propulsion force. Moreover, the flipper can be used according to the function by changing the shape into a shoe shape or flippers shape with a simple operation as needed when working underwater or walking underwater.
